Merge remote-tracking branch 'kraxel/usb.71' into staging

* kraxel/usb.71:
  usb-host: fix splitted transfers
  usb-host: update tracing
  usb-redir: Set default debug level to warning
  usb-redir: Only add actually in flight packets to the in flight queue
  ehci: handle dma errors
  ehci: keep the frame timer running in case the guest asked for frame list rollover interrupts
  ehci: Don't verify the next pointer for periodic qh-s and qtd-s
  ehci: Better detection for qtd-s linked in circles
  ehci: Fixup q->qtdaddr after cancelling an already completed packet
  ehci: Don't access packet after freeing it
  usb: host-linux: Ignore parsing errors of the device descriptors
  usb-host: scan for usb devices when the vm starts
  usb: Fix (another) bug in usb_packet_map() for IOMMU handling
  fix live migration
